Abstract

The utility model relates to a scroll compressor for a heat pump system. The scroll compressor comprises a motor shaft, wherein a motor coil and a motor rotor are sleeved outside the motor shaft. The scroll compressor is characterized in that a region positioned between a fixed vortex disk and a rear cover is divided into a left cavity, a middle cavity and a right cavity; an upper hole, a middle hole and a lower hole are formed in the bottom of the middle cavity; the middle hole is communicated with the left cavity and the right cavity through channels; a selective communicating mechanism linked with an electromagnetic valve core is arranged in the middle cavity; due to the change of the position of the selective communicating mechanism in the middle cavity, the middle hole is communicated with the upper hole or the lower hole. According to the scroll compressor, the axial distance movement of the electromagnetic valve core drives the selective communicating mechanism to do motion up and down in the middle cavity, so that the middle hole is communicated with the upper hole or the lower hole; a four-way valve can be omitted to realize conversion between refrigeration and heating after the scroll compressor is applied to the existing heat pump system.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of compressor, adopts after this compressor, and original heat pump can be cancelled four-way valve.

In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of heat pump scroll compressor, comprise that outer cover has the motor shaft of motor winding and motor rotor, eccentric mass is located on the output terminal of motor shaft, motor shaft drives movable orbiting scroll to do revolution motion and form crescent shape cavity volume with static vortex disk engagement around motor shaft center line by eccentric mass, rear at static vortex disk is provided with bonnet, it is characterized in that: the region between static vortex disk and bonnet is divided into left chamber, intermediate cavity and right chamber, in the bottom of intermediate cavity, be provided with hole, mesopore Ji Xia hole, mesopore via passage respectively with left chamber and right chamber conducting, in intermediate cavity, be provided with the selection conducting mechanism with valve core of the electromagnetic valve interlock, by selecting the change in location of conducting mechanism in intermediate cavity to make mesopore or the conducting of Yu Shang hole or the conducting of Yu Xia hole, at left chamber and right chamber, by left chamber hole provided thereon and right chamber hole and air aspiration cavity, be conducted respectively.

Preferably, described selection conducting mechanism comprises slide block, on slide block, be provided with a groove, one end of slide block connects described valve core of the electromagnetic valve, and the change in location by slide block in described intermediate cavity makes mesopore via groove or the conducting of Yu Shang hole or the conducting of Yu Xia hole.

Preferably, the spacing between described mesopore and described upper hole equals the spacing between described mesopore and described lower hole.

The utility model drives selection conducting mechanism to move up and down in intermediate cavity by the axial spacing motion of valve core of the electromagnetic valve, make mesopore or the conducting of Yu Shang hole or the conducting of Yu Xia hole, the utility model is applied to can cast out four-way valve to realize the conversion between cooling and heating after existing heat pump.

Embodiment

For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.

As shown in Figure 2, a kind of heat pump that the utility model provides arranges motor winding 2, motor rotor 3 and motor shaft 4 with the bottom of scroll compressor, two sections at motor shaft 4 arrange respectively a bearing 5, be provided with an eccentric mass 7 and be connected by straight pin 6 on the output terminal of motor shaft 4.The other end of eccentric mass 7 connects movable orbiting scroll 10 by a bearing.Movable orbiting scroll 10 bottoms by anti-from turn-taking 9 and anti-ly 8 limited to realize movable orbiting scroll 10 and do revolution motion around motor shaft 4 centers from shipping and reselling on another market.When motor is worked, by motor shaft 4 and eccentric mass 7, drive and anti-from turn-taking 9 and anti-from shipping and reselling on another market 8 restriction, make movable orbiting scroll 10 do revolution motion and form crescent shape cavity volume with static vortex disk 12 engagements around motor shaft 4 center lines, this crescent shape cavity volume constantly diminishes with the rotation of motor, and discharges from the central row pore of static vortex disk 12 bottoms.

In conjunction with Fig. 3 and Fig. 4, region between static vortex disk 12 and bonnet 17 has been divided into the BC of left chamber, intermediate cavity F and right chamber AD, in the bottom of intermediate cavity F, be provided with hole 16, mesopore 18Ji Xia hole 14, mesopore 18 via passage 18 respectively with the BC of left chamber and right chamber AD conducting, the spacing between mesopore 18Yu Shang hole 16 equals the spacing between mesopore 18Yu Xia hole 14.In the present embodiment, Jiang Shang hole 16 is connected with upper relief opening, the upper relief opening ，Jiang Xia hole 14 that is connected with indoor heat converter is connected with lower relief opening, lower relief opening be connected with outdoor heat converter (those skilled in the art also can exchange the interface of exchanger as required).In conjunction with Fig. 5, in intermediate cavity F, be provided with slide block E, one groove 13 is set on slide block E, one end of slide block E is connected with valve core of the electromagnetic valve, axial spacing Sports band movable slider E by valve core of the electromagnetic valve moves up and down at intermediate cavity F, makes mesopore 18 via

groove
